Ultra high definition TV is a must for more and more people. As we all know, Ultra HD TV is 4K TV, and full HD TV generally refers to 2K TV. 4K TV has better display effect than full HD TV, and there are corresponding 4K film sources to watch. The resolution of 4K TV is 3840 * 2160, which is four times higher than that of 1920 * 1080, about nine times higher than that of HD (HD. 1280 × 720). The resolution of 2K TV is only 1920 * 1080, the pixel is only more than 2 million, while the resolution of 4K TV is 3840 * 2160, the pixel is 8294400, and it can receive, decode and display the corresponding resolution video signal. The audience can see every detail, close-up in the picture, and have a real-life experience.
Now there are still many LCD TVs. The screen is composed of a large number of red, green and blue small LCD cells. The more the cells are, the more dense they are, the clearer the screen is. The picture of UHD TV is clearer than that of HD TV. Large size ultra-high definition TV play or watch ball games, more comfortable viewing effect. If you plan to switch to a new 4K Ultra HD TV, don't ignore the following 6 tips.
1. Confirm whether it is 4K Ultra HD display.
In addition to looking at the certificate of authority, you can also use your mobile phone to take a white picture, and compare the number of pixels of the same size screen with the same area or the same length. The number of pixels of the same size 4K screen is more than that of the 2K screen.
2. Check the chip.
Open the "factory menu" of color TV and enter "system information" to view "local information". See if the processor of the product is four core or above. Second, see whether the 4K decoding chip uses a professional 4K decoding chip.
3. Turn on the TV to watch the actual effect.
4. Check whether the interface meets the 4K TV standard.
Check whether the TV has USB 3.0 and HDMI 2.0 high-speed transmission ports. Check whether the 4K Ultra HD TV has a blue interface.
5. Check the operating system and whether there are streaming media applications and contents you like.
6. Don't neglect after-sales service
Good brand TV, its after-sales service will not be bad. Brand TV generally has a free warranty of one year for the whole machine and three years for other parts. In fact, the general brand TV, even if the TV has been out of the warranty period, after-sales call the other side will provide quite good technical support. TV is not fast consumable. We should make rational analysis according to our budget, real needs and personal preferences when we buy it.
